4.5. Battery Connection
For safe operation and compliance, a separate DC over-current protector or disconnect device
is required between the battery and the inverter. In some applications, switching devices may
not be required but over-current protectors are still required. Refer to the typical amperage in
the table below for the required fuse or circuit breaker size.

Please follow below steps to implement battery connection:
1. Please choose a suitable battery cable with correct connector which can well fit into the
battery terminals.
2. Use a suitable screwdriver to unscrew the bolts and fit the battery connectors in, then fas-
ten the bolt by the screwdriver, make sure the bolts are lightened with torque of 5.2 N.M in
clockwise direction.
3. Make sure polarity at both the battery and inverter is correctly connected.
4. In case of children touch or insects go into the inverter, Please make sure the inverter con-
nector is fasten to waterproof position by twist it clockwise.
Reverse Polarity
Before making the final DC connection or closing DC breaker/disconnect, be sure
po) must be connect to po) and negative(-) must be connected to
negative(-). Reverse polarity connection on battery will damage the inverter.
